[PyQt] Error building PyQt 4.8.1 as universal on OS X 10.5.8

[Brian Zambrano]

Building a universal version of my commercial PyQt has worked for me in the
past with these steps:

sip:

$ python configure.py --universal
$ make && sudo make install

PyQt:

$ python configure.py --confirm-license
$ make && sudo make install

I just upgraded to Qt 4.7, and am trying to build PyQt 4.8.1 with sip
4.11.2.  I'm on a 32-bit Intel mac mini with OS X 10.5.8.

It looks like a symbol is missing, but I'm not sure if that is from Qt or
PyQt:

$ cd PyQt-mac-commercial-4.8.1
$ make
